14 gru 2023 · Joisted Masonry buildings feature exterior masonry walls with floors and roofs made of combustible materials, offering moderate fire resistance, typically around one hour. In contrast, Masonry Non-Combustible constructions use non-combustible materials like concrete and metal throughout, resulting in higher fire resistance and increased safety.
Construction Class 4 (CC 4) holds many similarities to CC 2, joisted masonry. The key difference between these two classes is the wall and roof assemblies. Let’s look at their definitions.
14 gru 2023 · In contrast to non-combustible construction, which exclusively uses slow-burning or non-combustible materials, joisted masonry construction may incorporate combustible materials for roofs and floors. There are also similarities between joisted masonry and other construction classes.
6 lis 2023 · In joisted masonry construction, the walls are primarily composed of masonry materials such as bricks or blocks, while the roof is typically constructed with wooden joists and decking. On the other hand, in masonry non-combustible construction, both the walls and roof are constructed using non-combustible materials, such as steel or concrete.
15 lip 2024 · ISO 2, or Joisted Masonry, combines non-combustible masonry walls with a combustible wood frame roof. Exterior walls are typically made of brick veneer, concrete block, or similar masonry materials. However, the roof is usually supported by wood joists.
10 lip 2024 · For example, a masonry building may have an unprotected wood roof. The wood roof is the weakest member such that it has no fire-resistance. Thus, the construction class would be Joisted Masonry (see below). Now imagine this same building with a metal deck roof.
